I could see Palat aging similarly to how Zajac did. He's going to slow down, but he's not a guy who is overly reliant on speed to begin with. He's still going to be able to use his body to win battles along the boards, and he's smart enough to find ways to still be effective even as the feet and hands start to go away. This is assuming of course he stays relatively healthy and doesn't have injuries that start to pile up. But that's a concern for any player as they age.
